A legal fight is a matter of legislation. Should the laws shift within a nation, it becomes easier to shut them down, contrary to Bitcoin, which adheres to the immutable laws of mathematics and physics. Regardless of its legal status in any given country, Bitcoin persists as a force that requires billions of dollars to suppress.
That's certainly true, mate. Attacking Bitcoin would require hefty sums of money in order to be carried out with success. It's not really worth the cost. The bigger the network hashrate, the more money governments would need to spend to disrupt the Bitcoin blockchain.
At this point, I think it's safe to say that Bitcoin is "immortal". What governments will be able to do is shut down centralized mixers and exchanges alike. But the core Blockchain network will remain alive for the foreseeable future. This is is only the beginning. Who knows what will happen in the long run?
